Carbofuran Chemical Properties,Uses,Production


Carbofuran is a broad-spectrum carbamate insecticide and nematocide. It is an odourless, white crystalline solid. On heating, its breakdown can release toxic fumes and irritating or poisonous gases. It is sparingly soluble in water but very soluble in acetone, acetonitrile, benzene, and cyclohexone. The liquid formulations of carbofuran are classified as restricted use pesticides (RUP) because of their acute oral and inhalation toxicity to humans. Granular formulations are also classified as RUP.
In fact, carbofuran was first registered in the United States in 1969 and classified as RUP. Exposure to heat breaks down carbofuran, with the release of toxic fumes. Carbofuran is used for the control of soil-dwelling and foliar-feeding insects. It is also used for the control of aphids, thrips, and nematodes that attack vegetable, ornamental plants, crops of sunflower, potatoes, peanuts, soybeans, sugar cane, cotton, rice, and variety of other crops.

General Description

Carbofuran is an odorless white crystalline solid. Contact with skin may burn skin and eyes. When exposed to heat or flames Carbofuran may emit toxic oxides of nitrogen. Carbofuran is toxic by inhalation, skin contact, and/ or ingestion. Carbofuran is used as a pesticide.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

Carbofuran is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates. Carbofuran is unstable in an alkaline media. .

Health Hazard

Carbofuran is extremely poisonous. May be fatal if swallowed, inhaled, or absorbed through skin. Contact may burn skin or eyes. Probable lethal oral dose to humans 5 to 50 mg/kg or 7 drops to 1 teaspoon for 150 lb. person.

Health Hazard

The acute oral LD50 of carbofuran to male and female rats is about 8 mg/kg, while the acute dermal LD50 for rats is more than 3000 mg/kg. Carbofuran is mildly irritating to the eyes and skin of rabbits. The acute inhalation toxicity (LC50, 4 h) is 0.075 mg/L for rats. As with other carbamate compounds, carbofuran’s cholinesterase-inhibiting effect is short term and reversible. The symptoms of carbofuran poisoning include, but are not limited to, nausea, vomiting, abdominal cramps, sweating, diarrhea, excessive salivation, weakness, imbalance, blurring of vision, breathing diffi culty, increased blood pressure, and incontinence. Death may result at high doses from respiratory system failure associated with carbofuran exposure. Complete recovery from an acute poisoning by carbofuran, with no long-term health effects, is possible if exposure ceases and the victim has time to regain his or her normal level of cholinesterase and to recover from symptoms. Reports have indicated that risks from exposure to carbofuran are especially high among occupational workers and general public suffering with asthma, diabetes, cardiovascular disease, gastrointestinal or urogenital tracts disturbances. The available studies indicate carbofuran is unlikely to cause reproductive effects in humans at expected exposure levels. Studies indicate carbofuran is not teratogenic. No signifi cant teratogenic effects have been found in the offspring of rats given carbofuran (3 mg/kg/day) on days 5 to 19 of gestation

Health Hazard

Extremely toxic carbamate pesticide; routesof entry — ingestion, skin absorption, andinhalation of vapors; although the vaporpressure is very low [0.00002 torr at 33°C(91.4°F)], because of high toxicity, eventrace inhalation could be harmful; can causedeath if swallowed, absorbed through skinor inhaled; ingestion of about 0.5- to 2-gsubstance could cause death to humans; manifests acute, delayed, and chronic toxicity;choline sterase inhibitor; acute exposure maycause increased salivation, lacrimation, spontaneous urination, blurred vision, tremor,confusion, muscle twitching, and convulsion;high exposure may result in coma or respiratory collapse; other effects may includegastrointestinal effects, such as nausea, vomiting, abdominal pain, and diarrhea; cancause burn on skin contact; produced adversereproductive effects in experimental animals.
LD50 inhalation (guinea pig): 0.043 mg/L/4 hr(RTECS 1985 )
LD50 oral (rat): ~10 mg/kg
LD50 rat (skin): 120 mg/kg
Carbofuran hydrolyzes to less toxic 3-hydroxy carbamate and phenolic products.

Fire Hazard

May release nitrogen oxides. Containers may explode in heat of fire. Avoid alkalies. Stable under neutral or acid conditions.

Agricultural Uses

Insecticide, Acaricide, Nematicide: Carbofuran is a broad-spectrum carbamate pesticide that kills insects, mites, and nematodes on contact or after ingestion. It is used against soil and foliar pests of field, fruit, vegetable, and forest crops. Carbofuran, granule form, is banned in the U.S. A U.S. EPA restricted Use Pesticide (RUP). Not approved for use in EU countries. There are 40 global suppliers.. According to the Ecological Incident Investigation System, carbofuran has been responsible for more avian deaths than any other pesticide.

Effects may be delayed; keep victim under observation

Environmental Fate

Biological. Carbofuran or their metabolites (3-hydroxycarbofuran and 3-ketocarbofuran) at normal and ten times the field application rate had no effect on Rhizobium sp. However, in a nitrogen-free culture medium, Azotobacter chroococcum growth was inhibited by carbofuran, 3-hydroxycarbofuran and 3-ketocarbofuran (Kale et al., 1989). Under in vitro conditions, 15 of 20 soil fungi degraded carbofuran to one or more of the following compounds: 3-hydroxycarbofuran, 3-ketocarbofuran, carbofuran phenol and 3-hydroxyphenol (Arunachalam and Lakshmanan, 1988).
Plant. Carbofuran is rapidly metabolized in plants to nontoxic products (Cremlyn, 1991). Metcalf et al. (1968) reported that carbofuran undergoes hydroxylation and hydrolysis in plants, insects and mice. Hydroxylation of the benzylic carbon gives 3-hydroxycarbofuran which is subsequently oxidized to 3-ketocarbofuran. In carrots, carbofuran initially degraded to 3-hydroxycarbofuran. This compound reacted with naturally occurring angelic acid in carrots forming a conjugated metabolite identified as 2,3-dihydro-2,2-dimethyl-7-(((methylamino)-carbonyl)oxy)-3-benzofuranyl (Z)-2-methyl-2-butenoic acid (Sonobe et al., 1981). Metabolites identified in three types of strawberries (Day-Neutral, Tioga and Tufts) were 2,3-dihydro-2,2-dimethyl-3-hydroxy-7-benzofuranyl-N-methylcarbamate, 2,3-dihydro-2,2-dimethyl-3-oxo-7-benzofuranyl-N-methylcarbamate, 2,3-dihydro-2,2-dimethyl-3-benzofuranol, 2,3-dihydro-2,2-dimethyl-3,7-benzofuranol and 2,3- dihydro-2,2-dimethyl-3-oxo-7-benzofuranol (Archer et al., 1977). Oat plants were grown in two soils treated with [14C]carbofuran. Most of the residues recovered in oat leaves were in the form of carbofuran and 3-hydroxycarbofuran. Other metabolites identified were 3-ketocarbofuran, a 3-keto-7-phenol and a 3-hydroxy-7-phenol (Fuhremann and Lichtenstein, 1980).
Surface Water. Sharom et al. (1980) reported that the half-lives for carbofuran in sterilized and non-sterilized water collected from the Holly Marsh in Ontario, Canada were 2.5 to 3 weeks at pH values of 7.8–8.0 and 8.0, respectively. The half-lives observed in distilled water were 2 and 3.8 weeks at pH values of 7.0–7.2 and 6.8, respectively. They reported that chemical degradation of dissolved carbofuran was more significant than microbial degradation.
Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and Lewis, 1987; Lewis, 1990).
The hydrolysis half-lives for carbofuran in a sterile 1% ethanol/water solution at 25°C and pH values of 4.5, 5.0, 6.0, 7.0 and 8.0 were 170, 690, 690, 8.2 and 1.0 week, respectively (Chapman and Cole, 1982).


Carbofuran should be stored in a cool, dry, well-ventilated place, in their original containers only. It should not be kept stored or used near heat, open flame, or hot surfaces

Waste Disposal

Alkaline hydrolysis is the recommended mode of disposal. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.


During use/handling of carbofuran, workers should wear coveralls or a long-sleeved uniform, head covering, and chemical protective gloves made of materials such as rubber, neoprene, or nitrile. Occupational workers should know that areas treated with carbofuran are hazardous. The runoff of carbofuran material and the fi re control releases irritating or poisonous gases. It is advisable that workers should enter storehouses or carbofuran-treated close spaces with caution
